Packaging for products

ABSTRACT

A packaging for liquid food products is provided. The packaging has a flexible bag having a front wall having a transparent portion and a rear wall having, on the inner face, a distinctive region visible from outside through the transparent portion, when not covered by a product contained in the packaging.

The present invention relates to the field of flexible packaging havingthin walls, generally referred to as “pouches,” which are widely usedfor containing fruit juices or puree, yogurt, drinks and the like thatare mostly intended for consumption by kids.

Packaging of this kind is typically provided with a spout which has acap and, in the past, precisely in order to increase the children'sappreciation, solutions were developed which were provided with a capwhich also has a toy function.

For example, documents WO-A1-2014/083478, EP-A1-2489605 and theinternational application PCT/IB2018/056864, all in the name of theapplicant, describe caps which can also be used as toys.

The problem addressed by the present invention is that of providingpackaging which has features that are particularly attractive to achild.

This problem is solved by a pouch according to claim 1. The dependentclaims describe further advantageous embodiments.

The features and advantages of the packaging according to the presentinvention will become evident from the following description, given byway of non-restrictive example and in accordance with the accompanyingdrawings, in which:

FIGS. 1a and 1b show packaging according to an embodiment of the presentinvention;

FIG. 2 is a schematic view of a rear wall of the packaging according toan embodiment of the present invention; and

FIGS. 3a and 3b show packaging according to yet another embodiment ofthe present invention.

With reference to a first embodiment of the invention (FIGS. 1a and 1b), the reference sign 1 is intended to indicate, as a whole, a packagingor pouch.

The packaging 1 comprises a flexible bag 10 comprising a front wall 12which has lateral edges 12 a, 12 b, a lower edge 12 c and an upper edge12 d, and comprising a rear wall 14 which has corresponding lateraledges 14 a, 14 b, a lower edge 14 c and an upper edge 14 d; the frontwall 12 faces the rear wall 14.

The front wall 2 and the rear wall 4 are sealingly joined, preferablywelded, along the lateral edges 2 a, 2 b; 4 a, 4 b.

The bag 10 preferably also comprises a back wall (not shown) whichsealingly joins, preferably by means of welding, the front wall 12 andthe rear wall 14 at the lower edges 12 c, 14 c.

According to a variant, the lower edges 12 c, 14 c are sealingly joineddirectly to one another, preferably by means of welding.

Moreover, the upper edges 12 d, 14 d are preferably sealingly joined,for example welded.

Moreover, the packaging 1 preferably comprises a spout 3, which is heldbetween the walls 12, 14 at the upper edges 12 d, 14 d, and a cap 5 toclose the spout 3.

Each wall 12, 14 of the bag 10 consists of a flexible film, which ispreferably multilayer, which is impermeable to oxygen or permeable tooxygen.

According to the invention, the front wall 12 has a transparent portion20, i.e. a portion which is produced using a monolayer or multilayerfilm and allows the inside of the bag 10 or a product P containedtherein to be observed.

According to an embodiment, said transparent portion can be obtainedusing a multilayer film which consists of PE-PET-PETHB (from the insideout).

Said transparent portion 20 is preferably entirely contained on thefront wall 12.

Moreover, said transparent portion 20 is preferably delimited by awindow edge 22 having a geometric shape, e.g. circular, elliptical orpolygonal, or with a fanciful shape.

Furthermore, according to the invention, the front wall 14, which has anouter face 14 e facing the outside and an inner wall 14 i facing theinside of the bag 10, has, on the inner face 14 i, a distinctive region30 visible from the outside through said transparent portion 20 of thefront wall 12, when not covered by the product P.

The distinctive region 30 is distinguishable from the remaining part ofthe inner face 14 i of the rear wall 14, for example by a particularchoice of colors or by the presence of a meaningful or fancifulinscription or distinctive signs 32. In other words, said distinctiveregion 30 has graphic signs or color patterns which distinguish saidregion from the remaining part of said inner face 14 i.

For example, as the window edge 22 of the transparent portion 20 isprojected orthogonally on the inner face 14 i of the rear wall 14, aprojected region is obtained, and said distinctive region 30 iscoincident or contained within said projected region 16 (FIG. 2).

According to an embodiment, the distinctive region can be obtained bymeans of a multilayer film which consists of PE-PET-PETHB orPE-PET-ALU-PET (from the inside out), in which the layer of PE-PETprotects against the ink used to mark the distinctive signs.

FIGS. 3a and 3b illustrate a further embodiment of the invention; inthese figures, the same reference signs are used as in FIGS. 1a, 1b and2.

FIGS. 3a and 3b illustrate packaging 1 provided with a bag 10 havingsides 18 a, 18 b which are sealingly joined, typically by means ofwelding, to the respective lateral edges 12 a, 14 a; 12 b, 14 b of thefront wall 12 and the rear wall 14.

Innovatively, the invention provides flexible packaging which can beparticularly appreciated by children, in that it is provided with a playaspect which consists in discovering the distinctive region inside thebag through the transparent portion of one wall, when the product isconsumed.

It is clear that a person skilled in the art, in order to satisfycurrent needs, could modify the packaging described above entirelywithin the scope of protection as defined in the following claims.
